> *BACKGROUND*
>     Groovy home-made data structures are lack of maintainence for a long time, so it's better to replace them with mature and continuously improving data structure from JDK
> *SCOPE*
>  # Deprecate redundant {{AbstractConcurrentMapBase}}, {{AbstractConcurrentMap}}, {{ManagedConcurrentMap}}, and their related inner classes, e.g. {{Entry}}
>  # Replace {{ManagedConcurrentMap}} with {{ManagedIdentityConcurrentMap}}, which is base on {{ConcurrentHashMap}}
>  # Deprecate {{ComplexKeyHashMap}}, {{SingleKeyHashMap}} and {{TripleKeyHashMap}}. Note: {{TripleKeyHashMap}} is only used by never called method
>  # Polish {{Index}} and {{MethodIndex}} in the class {{MetaClassImpl}}, they derive from {{SingleKeyHashMap}}
> *BENEFITS*
>  # Better maintainence and readability
>  # Continuously improving data structure from JDK
> *PULL REQUEST*
>  * [https://github.com/apache/groovy/pull/1306]
